To the ancient Greeks she was originally the organizer of the "communal affairs of humans, particularly assemblies".[1]Moses Finley remarked of themis, as the word was used by Homer in the 8th century BCE, to evoke the social order of the 10th- and 9th-century Greek Dark Ages:

Themis is untranslatable. A gift of the gods and a mark of civilized existence, sometimes it means right custom, proper procedure, social order, and sometimes merely the will of the gods (as revealed by an omen, for example) with little of the idea of right.[2]

Finley adds, "There was themis—custom, tradition, folk-ways, mores, whatever we may call it, the enormous power of 'it is (or is not) done'. The world of Odysseus had a highly developed sense of what was fitting and proper."[3]

The personification of abstract concepts is characteristic of the Greeks. The ability of the goddess Themis to foresee the future enabled her to become one of the Oracles of Delphi, which in turn led to her establishment as the goddess of divine justice.

Some classical representations of Themis showed her blindfolded, holding a sword. The sword is also believed to represent the ability Themis had from cutting fact from fiction; to her there was no middle ground. Themis built the Oracle at Delphi and was herself oracular. According to another legend, Themis received the Oracle at Delphi from Gaia and later gave it to Phoebe.[4]

When Themis is disregarded, Nemesis brings just and wrathful retribution; thus Themis shared the Nemesion temple at Rhamnous. Themis is not wrathful: she, "of the lovely cheeks", was the first to offer Hera a cup when she returned to Olympus distraught over threats from Zeus.[5]

Themis presided over the proper relation between man and woman, the basis of the rightly ordered family (the family was seen as the pillar of the deme), and judges were often referred to as "themistopóloi" (the servants of Themis). Such was also the basis for order upon Olympus. Even Hera addressed her as "Lady Themis." The name of Themis might be substituted for Adrasteia in telling of the birth of Zeus on Crete.

Hesiod's description and contrast to Dike

In Greek mythology, Hesiod mentions[6] Themis among the six sons and six daughters of Gaia and Uranus (Earth and Sky). Among these Titans of primordial myth, few were venerated at specific sanctuaries in classical times.

Themis occurred in Hesiod's Theogony as the first recorded appearance of Justice as a divine personage. Drawing not only on the socio-religious consciousness of his time but also on many of the earlier cult-religions, Hesiod described the forces of the universe as cosmic divinities. Hesiod portrayed temporal justice, Dike, as the daughter of Zeus and Themis.

Dike executed the law of judgments and sentencing and, together with her mother Themis, carried out the final decisions of Moirai. For Hesiod, Justice is at the center of religious and moral life, who, independently of Zeus, is the embodiment of divine will. This personification of Dike will stand in contrast to justice viewed as custom or law, and as retribution or sentence.[7]

Children

The only consort for Themis mentioned in the sources below is Zeus. One of her few children was called Natura, the Greek goddess of the forest.

Horai: the hours

With Zeus she more certainly bore the Horae,[8] those embodiments of the right moment – the rightness of order unfolding in time – and Astraea.

Second generation

Moirai: the fates

Followers of Zeus claimed that it was with him that Themis produced the Moirai, three fates.[9] A fragment of Pindar,[10] however, tells that the Moirai were already present at the nuptials of Zeus and Themis; that in fact the Moirai rose with Themis from the springs of Okeanos the encircling world-ocean and accompanied her up the bright sun-path to meet Zeus at Mount Olympus.

Justitia

A Roman equivalent of Dike, the daughter of Themis and Zeus and personification of one aspect of Hellenic Themis, as the spirit of the divine rightness of law, was Iustitia (Anglicized as Justitia). Her origins are in civic abstractions of a Roman mindset, rather than archaic mythology, so drawing comparisons is not fruitful. Portrayed as an impassive woman, holding scales and a double-edged sword (sometimes a cornucopia), and since the 16th century usually shown blindfolded, the sculpted figure outside a courthouse is typically Justitia or Lady Justice, not Themis. In the law courts at Vancouver, British Columbia, however, the statue is explicitly of Themis.
